Hi all

After suffering rod end bearings for the last 4 years I want to move to a
BB pivot.

However I am unsure how you make it adjustable so you can ensure the tapers
are well bolted up to stop the BB rattling between the pivot anchors [
being either pedal cranks[ original design ] or a built up *[* shape ? ]]
